FAN ATTACHMENT.

SPECIFICATION forming part of Letters Patent No. 446,584, dated February 17, 1891.

Application led November 21, i890. Serial No. 372,189. (No model.)

To @ZZ whom 'it may concern.-

Be it known that I, GEORGE S. NICKUM, a citizen of the United States, residing at Dayton, in the county of Montgomery and State of Ohio, have invented certain new and useful Improvements in Fan Attachments, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this speciiication.

My invention relates to Ventilating-fans for dining-rooms, stores, saloons, and the like,

Y which are usually suspended from the ceiling and are rotated by power; and it has for its object the improved construction of the fan-hub and its associated parts, whereby the fan can be stopped and started at will in a very simple manner, and whereby the fanblades can be given, simultaneously,*any dcgree of angling desired.

The novelty of my invention will be herein set forth, and specilically pointed out in the claims.

In the accompanying drawings, Figure l is a perspective view of a ceiling-fan embodying my invention.` Fig. 2 is an enlarged central section in elevation through the fan-hub and its associated parts locked together. Fig. 3 is a corresponding view with not so much in section and with the parts unlocked. Eig. A is a detail in elevation and partly in section showing the application of my invention to a column-fan. Fig. 5 is a detail sectional view representing a modification in the construction.

A is the usual or anv suitable bracket-support; B, the tubular socket for the fan-shaft C; D, the driving-pulley, and E the belt for rotating the fan-shaft. Journaled upon the lower part of the shaft C between a fixed collar F upon the shaft and a pin or lug u, projecting froln the shaft within the hub, is the hollow fan-hub G, having radially-projecting tubular sockets ZJ-in this instance four in number-set quartering. In each of these sockets is journaled a socketed spindle II, having on its inner end a beveled pinion c j ust within the hub G. A set-screw d through each socket l), confined in a circumferential groove in each of the spindles, serves to lock the latter in place without preventing their "crown-gear J, meshing with all of the pinions c and held in place, though free to revolve, by set-screws f, passed through the lower part of the hub G and confined in a circumferential groove in the gear J. The lower side of the gear- J is serrated, as shown at g, Fig. 3,

or otherwise formed, to constitute the upper half of a clutch.

Journaled upon the shaft Gand inserted into the hub G through the opening in the annular gear J is a sleeve K, having at its upper end on one side a pin 7L, which is eon fined in an aperture 1l in the top wall of the hub, and on the other side a slot or groovej, into which the pin a lits and is locked, as seen in Fig. 2. At the lower end of the sleeve K is a circular spider iiange or disk L, whose upper surface is serrated to form a half-clutch to engage with the half-clutch upon the under side of the gear J.

A coiled spring M, surrounding the lower` end of the shaft O and put under tension in any suitable manner-in this instance by a washer 7c and screw Z-bears at its upper end against the lower end of the sleeve K and serves to hold the latter up both to lock the clutchfaces and hold the pins a and h in their respective apertures j and In this position (represented in Fig. 2) the parts are all firmly locked together. The hub G is locked to the sleeve K bythe pin 7i, and the shaft G is likewise locked to the sleeve K by the pin a. The clutch-faces beingengaged, the gear J is locked to the shaft C and the spindles II are held. from rotation or adjustment ou their axes.

as this is done the rotation of the shaft C can Screwed upon the flange L of the lower half- ICO 4o gether.

ries the pin a over the top edge ot the sleeve K, as seen in Fig. 3, and holds it down with the spring )I under tension. once released, and the hub G is loose upon the shaft C and will not revolve; or, il it does,

will revolve very slowly and merely by friction, as will be readily understood. \V hen in this position,the gear J is freed and the tanblades can be angled simultaneously by taking 1o hold of any one of them and turning it as desired. Through the medium of the pinions c and gear J all the other fan-blades will be correspondingly turned, and it is to be observed that there is no limitation whatever as to the.

x5 degree of angling of the blades,` whether to throw the air up or down. To relock the fanhub to the shaft and to rclock the spindles Il, it is only necessary to again grasp the cup N and hold it until the pin a travels around,

2o registers with its groove j, and becomes partially locked therein. The sleeve K then, traveling with the shaft C, brings the pin h around to its socket i, and the spring M, being thereby released, forces the sleeve K up and re-enz 5 gages the clutch-surfaces and locks all the parts, as will be readily understood.

Vhile I have shown the grasping-handle N as a detachable drip-cup, such form of handle is not essential, as any handle for disengaging the pinsv and clutch-faces might be substituted. Again, the pin a and groovej may be dispensed with, as in Fig. 5, where a collar fm, is made fast to the fan-shaft within the hub and upon which the latter rests. This collar has a perforation n through it registering with the opening c' in the hub, and the pin h is made sufficiently long to pass through thc perforation n in the collar and into the openin g v1f to lock all the parts securely to- To unlock them it is only necessary to draw down the sleeve li until the pin h is freed from the perforation u, whereupon the sleeve is partially turned and the pin bears against the nuclei' side of the collar, as shown by the dotted lines, Fig. 5.

Again, while I have described the application of my invention to ceiling-fans, which necessitates the employment of the spring M, yet it is to be understood that the invention 5o is capable ot application to column-fans, as

in Fig. +L, where the use of the spring is not necessary and is dispensed wit-h, as is also the grasping-handle in the form ot a drip-cup.

In Fig. e the parts are inverted and the sleeve K is held with its pins and clutchfaces engaged by gravity alone, and to unlock the parts it is only necessary to lift the sleeve by grasping its attached or integral handle N.
